北京新航道为托福考生提供托福考试指导和建议。在托福考试中，若说词汇是基础，那么语法就是脉络，支撑着所有的题型。对同学来说，语法是令人头疼的，从开始接触，到学已数载，可能还是没弄明白。其实，语法并不是那么难懂，只要用心去揣摩，多做练习，就会潜移默化的懂了。在这里，我们针对托福考试中的语法进行分类解析，帮助考生复习，重拾语法信心。
某些副词之后的倒装
某些副词和副词短语，主若是一些含有限制或否认意义的副词和副词短语，为了暗示强调可放在句首，这时后面应跟动辞书倒装(即疑问)形式。这类副词或副词短语中最主要的有：
hardly ever
on no account
hardly…when
only by
in no circumstances
only in this way
neither/nor
only then/when
never
scarcely ever
no sooner…than
scarcely…when
not only
seldom
not till
so
nowhere
例句如：
—I haven’t got a ticket.
—Neither/Nor have I.
—我没有票。
—我也没有。
I had never before been asked to accept a bribe.相当于：
Never before had I been asked to accept a bribe.
以前从来没有人试图向我行贿。
They not only rob you，they smash everything too.相当于：
Not only do they rob you，they smash everything too.
他们不仅抢劫你，而且砸烂所有的工具。
He didn’t realize that he had lost it till he got home.相当于：
Not till he got home did he realize that he had lost it.
一向到了家，他才觉察那工具丢了。
This switch must not be touched on any account.相当于：
On no account must this switch be touched.
这个开关严禁触摸。
He was able to make himself heard only by shouting.相当于：
Only by shouting was he able to make himself heard.
他只有叫嚷才能让别人听到他。
He became so suspicious that…相当于：
So suspicious did he become that…
他变得这样疑心，甚至……
注重：在一个句子中，第二个否认动词有时可以用nor来表达，并跟倒装语序：
He had no money and didn’t know anyone he could borrow from.
He had no money，nor did he know anyone he could borrow from.
他身无分文，也不熟悉任何可以捐钱的人。(neither在这儿不太常用。)(关于副词和副词短语后跟动辞书倒装语序和作主语的名辞书情形，如Up went the rocket<火箭直升飞起>， By the door stoodan armed guard<门口站着一名手持刀兵的士兵>
上面就是关于用形容词表示类别和整体的解析。考生们切记要搞懂，理顺了脉络，做起题来才会得心应手。掌握好语法是关键。另外，考生们要记住一点，万变不离其宗，不要换个样子就不会了，活学活用贯穿始终。祝考生考出理想成绩。
